Hello Greg, Have you ever seen an Essemtec in a real production run? I have. But actually placing BGA, MicroBGA with their Cyber optics laser alignment? Or with the supplementary camera (I think it was with a VGA resolution)? Well, that�s something

Sounds like it would by tough to justify, thought of oursourcing? if the volume is really that low I bet it would be cheaper to find an outside source to build them for you. As far as hand placment accuracy If you are hand placing BGA's or even worse

I worked with a few BGA rework stations and also had the chance to see several demos on different brands. THe good ones that can really do it are equipped with camera, infrared under the board, different nozzles and a hot air comming from the head(di

| Dear all, | | We've got a curious problem. We have had a major problem with BGA's occasionally being placed one to several rows or columns off the pads. We are using Universal's GSM2 platform for our general purpose placements. Our Universal re

Thanks aj, Ohh I wish that there was a way to post a picture in this forum or a possibility to attach the datasheet... Which BTW does not have any recommendation of "how to". This package does not have the "center thermal pad" like a QFN or MLF pack

I have a situation with hot boards with fine pitch BGAs that I need to build. However, there is a big problem--the auto screen printer is down. I decided that we would use the stencil and manually line up the pads and do a manual print. I can't ac

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w

| Which is the preferred method for soldering a bga, adding solder paste or not? Solderpaste manufacturers say to add solder while the rework station manufacturer's say it's not necessary. | Paste is preferred by not necessary. Our studies, conduct
